Thousands remember "People's Princess" in London
Lady Di's life was short, but it was very rich with events, both joyful and tragic.
Every step was pictured and talked about in the tabloids, especially her unhappy marriage to Prince Charles.
But she won the hearts of millions of ordinary people by her dedicated work for peace in the world and tender relationship with her sons.
The princes were warmly welcomed by the crowd at Wembley Stadium.
“This evening is about all that our mother loved in life – her music, her dance, her charities, and her family and friends,” said Prince William, Princess Diana's son.
And the world's most popular singers paid tribute to her.
